Answer: Theresa needs to babysit for 3 hours
Step-by-step explanation:
Given that theresa has $3 while she needs $25.50, and makes $7.50 per hour, find the number of hours she needs to work to make the balance she needs.
First, we find the difference between what she has and what she needs= $25.50 - $3
=$22.50
Then, to get the balance she needs, we divide $22.50 by $7.50
=22.50/7.50 = 3hours
